Description
Open Image dialog uses embedded thumbnails if available in the file. (i have only seen this on jpeg-files but it might work the same way for other files).
i have set the preferences to show large thumbnails (256x256). however when the open image dialog finds an embedded thumbnail in a jpeg file the embedded thumbnail will be used no matter the size of it. in my case this equals that images with embedded thumbnails display much smaller thumbnails then the rest of the files. normally one can force a thumbnail reload using Ctrl-ClickLeftMouse, but this does not work on files with embedded thumbnails.
